She explained, “She’s in her thirties. She’s my half sister and I talked to her for the very first time in my life around when I turned 20.”

Demi recalled, “I asked her, ‘Why haven’t you ever contacted me?”- and she just said, ‘Well, because I never wanted you to think I wanted anything from you. So I’ve just kind of been waiting to see if you wanted a relationship,’ and I just thought that was so incredible.”

The Heart Attack singer was then asked about her Valentine’s Day date dinner with Wilmer Valderrama.

She replied, “Some things you just have to keep to yourself. No, I would not like to comment.”

Meanwhile she just performed in Orlando and Texas and has been tweeting photos and videos from her gigs.

She also wrote on March 5, “I’ve got the #1 most added song in the country this week!! Thank you Radio!!! Thank you fans!!! #UNREAL”
